Solution for Cover Glass AOI

The glass cover of a mobile phone is the outermost glass of the touch screen. With the rise of smartphones, glass covers are widely used in the electronics industry. They are attached to the surface of touch screens to protect the screen and beautify products. The automatic detection of cover plate defects is considered a technological bottleneck that has plagued the industry for many years in the field of smartphones. Surface defect detection of products requires high detection accuracy and reliable lighting effects to ensure it. Especially the difficulty of detecting the glass of the phone cover after lamination is greater.

 

The glass cover detection solution can detect white film and silk screened covers, and is compatible with 3D glass cover detection. It can also perform defect detection on car glass screens and LCD screens.

 

 

Solution Features
  • Compatible with 3D glass cover detection

     

  • High resolution

    High resolution linear array camera, equipped with high-resolution line scanning objective lens, the field of view width can be determined according to resolution requirements, high resolution can improve detection accuracy;

  • See the effect of 'defects'

    By designing a special angle light source and controller, a product can obtain multiple images with different angles and brightness, successfully simulating various light angles and perspectives during manual visual inspection, presenting defects in the image, truly achieving the effect of "seeing" defects, and providing rich raw materials for image algorithms in later machine vision inspection software.

  • Servo motor drives rubber wheel conveyor line to transport materials

    Ensure that the material movement speed is relatively stable, and use a line scan camera to capture images during movement.。

 
Recommended solution
TFT-LCD edge Burr Check AOI

The TFT-LCD edge inspection machine is developed and produced by Fuxin Optoelectronics. Based on machine vision and AI artificial intelligence technology, the TFT-LCD edge inspection machine integrates optics, mechanics, electronics, software, and algorithms. It is mainly used for automatic detection of edge defects in the TFT-LCD production process, achieving machine replacement. In practical applications, suspected defect areas are extracted from the edge sample images of TFT-LCDs after image processing, and judgment criteria are established to effectively eliminate interference. The types of defects such as edge extension, shell, edge collapse, and corner collapse are successfully determined, and the criteria are established to avoid repeated judgments and detect multiple defects simultaneously.

Glass Cover AOI

The glass cover of a mobile phone is the outermost glass of the touch screen. With the rise of smartphones, glass covers are widely used in the electronics industry. They are attached to the surface of touch screens to protect the screen and beautify products. The automatic detection of cover defects in the field of smartphones is considered a technological bottleneck that has plagued the industry for many years. The detection of surface defects in products requires high detection accuracy and reliable lighting effects to ensure, especially for the detection of glass cover plates after lamination, which is more difficult. At present, the device can detect white film and silk screened cover plates, and is compatible with the detection of 3D glass cover plates. It can also detect defects in car glass screens and TFT-LCDs.
